Abstract
The invention relates to a symmetrical beam-splitting filament-spreading double-lower support 2*2 shafting composite yarn, a spinning method and application. The composite yarn is a 2*2 shafting mesh wrapping, mesh wrapping and coating and mesh coating composite yarn which is compounded after two filament meshes respectively support and wrap short fiber whisker strips from downsides; and the composite yarn can be used for weaving soft, abrasion-resistant, beautiful and comfortable textiles with clear texture, high intensity and pilling resistance and high-level fine fabrics. The method for producing the composite yarn comprises the steps of: adopting a yarn guide hook, a splitter, a beam concentrator and filament spreading devices all of which are mounted on a ring throstle; after splitting the filament into two beams by using the splitter, downwards guiding the beams by left and right filament guide hooks and feeding the beams into respective filament spreading devices for filament spreading in a centering manner and forming tow paths of lower-supporting filament meshes; enabling the spread filaments and the short fiber whisker strips located by the beam concentrator to enter into the front roller in a manner of upper and lower layers; wrapping respective short fiber whisker strips in a twisting triangular zone and compounding to form the composite yarn. The method is suitable for spinning of protective, soft, smooth and high-count and superfine composite yarns of fibers which are ultra-short, easy to drop scraps and easy to generate flying and shorter and weaker fibers.
Description
Technical field
2 * 2 axles that the present invention relates to a kind of beam splitting of spinning in field and the two subiculum protections of exhibition silk are composite yarn, the spinning method of this composite yarn, the application of this composite yarn and the application of this spinning method.
Background technology
Along with the fast development of textile industry, the noil in textile process process, short, the on the weak side fibrid of fuds fuddled isogonic increase; Reuse textiles gained fiber is compared with fibrillation with in intensity in length, has certain gap; Some new ultrashort, fragile fibers, as kapok, eider down etc., start to be concerned and to utilize.And the spun yarn strength of these fibers partially short, class on the weak side is low, and filoplume is many.So just cause this class fiber partially short, on the weak side not to be fully utilized.
Meanwhile, in the processing of existing long filament for convenience of and high yield, all produce thicker long filament, the line density value of conventional variety is greater than 30D (DENIER).If high-count yarn spun, is more than or equal to the yarn of 80S (public), a threads Shu Benshen will account for the more than 30% of composite yarn quality.Therefore the conventional long filament of two bundles almost will account for the more than 60% of composite yarn quality, more than individual staple fibers yarn just reaches 150S, if two staple fibre yarns are exactly more than 300S, this is even drawing-off resultant yarn almost, because only have several to tens staple fibres.Therefore, select the long filament of low dawn number≤20D, beam splitting is the endless tow below 10D even again, is the necessary of high of spinning or ultra-fine (>=120S) yarn.
In the prior art, the be as the criterion report that has no of individual layer filament layer of relevant endless tow compartition, the patent continuous tow dispersing device (patent No. CN1811025A) that close patent is as strong in horse is random dispersion, is not to be divided into accurate individual layer, it is mainly comprised of air separator and carding, in air separator, there is hollow cylinder, its upper port has sub-wire chamber, bottom surface, sub-wire chamber is the wire sub-panel that is distributed with some passages, combing groove is housed in carding, this gas separate mode is not suitable for the spinning of staple fibre yarn, because can strengthen the disorder of flyings and yarn.The patent of Yu Mingwei is decomposed into tow the receiving/releasing volume Apparatus and method for (patent No.: CN1884026A) be comprised of minute reed device and tenslator of parallel filaments, by tenslator, control tension force, by the centrifugation of sub-wire reed, tow is resolved into parallel filaments.The patent bundle fiber of Joseph Lee Lifke divide from method and apparatus (METHOD AND APPARATUS FOR SPEREADING FIBER the BUNDLES) (patent No.: US6049956) formed by several dispersion drums, by change, disperse the angle of drum two ends disk that bundle dividing is scattered, many, the mechanical concertednesses of the method plant machinery parts require high.
Above-mentioned each correlation technique, one, is all that to take the outstanding fiber of spinnability be object, the spinning that changes resultant yarn style and fancy or high Zhi Huawei object, cannot utilize spinnability fiber poor or that at all cannot spin; Its two, be more suitable for the high branching of partially short fiber on the weak side, even superelevation branching spinning.
Summary of the invention
An object of the present invention is to provide a kind of can effectively utilize partially short, on the weak side, difficulty is spun, the tradition not composite yarn of fiber-spinnable that spins even.Another object of the present invention is to provide a kind of spinning method of above-mentioned composite yarn, to provide the height of high row yielding to prop up the bright and clean composite yarn of an even ultra-fine softness.Another object of the present invention is to provide a kind of application of above-mentioned composite yarn.Another object of the present invention is to provide a kind of application of above-mentioned spinning method.
In order to achieve the above object, a technical scheme of the present invention has been to provide the two subiculums 2 of a kind of symmetrical exhibition beam wire, and to take advantage of 2 axles be composite yarn, it is characterized in that: thereby wrapped up in to twine after staple fibre yarn again by monofilament holder off the net, compoundly form 2 and take advantage of 2 shafting structures, it has four kinds of forms, wherein, the first is: the holder off the net of a pair of monofilament is wrapped up in and twined staple fibre yarn Hou Fu Merger, and called after lower bearing screen is wrapped up in composite yarn; The second is: a silk screen subiculum is wrapped up in and twined staple fibre yarn and a silk screen looping staple fibre yarn Hou Fu Merger, called after net wrapped mesh bag composite yarn; The third is: multiple Merger after a pair of monofilament net looping staple fibre yarn, called after net bag composite yarn; The 4th kind is: the holder off the net of a pair of wider monofilament and expose looping staple fibre yarn after multiple Merger, be that net is wrapped up in and netted to wrap and be stored on a silk screen and wrap up in and twines staple fibre yarn, called after is partly wrapped up in bag composite yarn;
